Figi. k5vis aview similar to Fig-4 but shows the parts-intheir operated positions. A Y yVVhilethe commercial phonograph or dictation machine shown in the-accompanying drawings is of thertranscr'ibing type, the invention is not limited to use in connection with this :kind of a machine', .but is also applicable to other machines such as dictating machines and combined dictating and transcribingrmachines, also other rphonographs. y

Thefmachine shown comprises a base V10, containing a 'drivingmotorhll and speed governing 'mechanisnm The top of the'icassusY ing is constitutedby a table 12Lhaving Y formed integral therewith a housing 13v for supporting a mandrel 14 adapted to ,carry va record lwhich is to Vbe repiOCluCd- The table 12 also has verticalfstandards i i is provided; rlhisY .clutch member 22 is adapted to cooperate withy a clutch member 23 secured to a pulley 24 whichis constantly rotated while thevmachine. is in use by the'V motor 11 through a1 belt lnusing the machine, the clutch member 22.isA moved into and out ofengagement with the continuously operating clutchmember 23 by the operator through mechanism not shown and of nohcionsequence in connectionfwith the H s is lmounted::upon a l shaft ongwliose end a movable.. clutch member 22 present invention. Suiiice it to say, that even when the clutch member 22 is disengaged from the clutch member 23 the pulley 24 continues to operate, being at all times positively driven through the belt 25 by the motor 11.

It frequently occurs in the use of the machine that the operator desires to revert to a portion of the record just passed to verify the transcription or to again listen to something which was not entirely clear. facilitate this, the machine is provided with a back-space mechanism comprising a keylever 26 having a'hub 27 carried by the sound-box carriage and upon which is mounted a pawl 28 adapted to co-operate with a tooth rack 29 supported upon the standards 16 and 17 directly above the upper guide rod 18. y

AVhen the back-space hey-lever 26 is depressed the pawl 28 engages the rack 29 an-d forcesithe carriage backwardly i. e. toward the left, in Fig. 1. In operating, the backspace key-lever 26 also raises the nut 22 from the feed-screw 21 to free the carriage therefrom for this backspacing movement. It may or may not, as desired, raise the stylus from the recordsurface during this backspacing movement, and so far as this invention is concerned, itv is immaterial [whether it does or not. Y

For a more complete understanding of the back-space mechanism above described, attention is called to the patent to Macdonald :li-1,030,740, June 25, 1912, fully disclosing the same.

Since the operator is usually some -distance from the machine, receiving the sound from the sound-boX 30 through a eXible tube 31, l

it is sometimesinconvenient to reach over to the machine to operate the back-space key-V lever 26. To avoid the'necessity for doing this, the present invention provides means operatedy by the motor 11 for actually performing the back-spacing operation, this means being controlled from the type-writing machineor other point remote from the phonograph byian easily operated device,Y

such as a Bowden wire.

In order that the device may be placed uponv a phonograph as an attachment soit can be applied to existing machines, there is provided a mainA support 32 adapted to embrace the standar-d 16, or other convenient support, and to be secured'thereto by screws 33 andan auxiliary support 34 adapted to embrace the standard 17, or other convenient support, and to be secured thereto by screws 35. These supports 32' and 33 each have upn standing arms '36 rotatably supporting a transverse rod or shaft 37 in which is mounted a'universal bar or vane38 of such length and rso positioned as to always be and 5. The provision of the bail formed by the rod 37 and the vane 38 in this position, in itself constitutes a valuable feature, for when used alone without any operating mechanism, it permits the operator to act-uate the back-space key-lever 26 by pressing directly uponthe vane 38 at any point irrespective of the position of the carriage 20. Hence, it is not necessary for the operator to first locate the position of the key-lever 26 and then operate it, but may press the vane 38 anywhere in'its length to obtain the same result. Y y

However, in orc er that the vane may be automatically operated, the: end of the rod 37 adjacent the pulley 24 isprovided with a forked-lever 39 into which extends a pin 40 Icarried by an arm 41pivotally mounted upon a screw 42 mounted in the standard 16. The arm 41 has coupled to it (byra pin 41a) for rotation upon the screw 42, altrip-lever 43whose rear-end 44 is adapted to engage one or more cams 45 mounted upon the drive ing pulley 24, so that when the trip-lever 43l` is in position to be engaged by. the 'ca-ms, 45, its rear-end 44 is raised while thev forward end is depressed. :Through the Vcoupling of the forward end of the trip-lever 43 with the lever41, by the pin 41a, the lever 41 is also rocked downwardly, carrying withl it its pin 40 which rides in the forked-arm 39 and rocks the rod 37 clockwise, as seen in Figs. 2, 4 and 5. This operation` causes the vane 38 to engage the top of the key-lever 26 and depress the latter which results in a backspacing movement being imparted to the carriage 20 bythe mechanism heretofore` described. i I

Ifv the trip-lever- 43 were allowed toV normally remain in position to be engaged by theA cams 45,. the rod 37 would os'cillate continuously until .the carriage reached its rearmost position,"and, of course, this is not usually desired. Therefore, in order that the operation of the back-space mechanism may be intermittent and may bev fully controlled by the operator, the trip-lever 43 is normally held in inoperative position, that shownz in y Fio'. and` an ear 48 bent laterally from the support-*'32,* Normally the control-lever V46 is. held by a spring46a so that its upper Vend49, which 1, ,by a control-lever 46 (see Figs. 4

kinclines laterally and constitutes a cam, en`

gages a forwardly extending arm 5 0 of the trip-lever, and causes the rear| end of the latter to be cammed to the right, as shown in Fig. v1,l against thetension of a spring 51 interposed between it and the 'head' of the pin 41.@ so as to normally be outof range of the cams 45 on the pulley 24.' y

vWhen it is desired to operate the bachspace mechanism by the VYpoweroffthe machine transmitted tothe" pulley 24, the rcon- ,30

trol 'lever 46 is manually'operated as by the pivoted upon alsc'rew 47 secured in i depression of a keylever` 52 to remove the cam portion 49 of the control-lever from-the arm 50 of the trip-lever. This allows the spring 5l to cause the end 44 of the trip-lever to move into the path ot Athe cams so that, when the -cains 45 reach the trip-lever, it will oscillate and through the mechanisml above described cause the oscillation ot the rod l? and the consequent operation ot the bacio space key-lever 26. 1 I f K When the control-lever 46 is operated, itl is held in operated position until .the trip lever itself operates, by reason of the engageinent Vof the control-lever with the "lorward end 52 of the arm 50, see Figs. 2 and 3.- Then, when the trip-lever 43 is moved by one of the cams 45 and reaches the limit of its movement,'the end 50 passes down beyond the cam surface 49 of the control lever to allow the latter to move rearwardly toits normal position. `The trip-lever, in returningtoA normal positiomcauses its end 50 to engage the cam por-tion 49' of*y the control-- lever and this causes the rear end 44 ot the trip-lever to be cammed to its normal inopperative position shown inY Fig. l. Thetrip-v lever i3 remains in vits idleposition until the control-lever 46 is again operated. The trip-leverand its connected' parts, including the vane 38 and rod 37, are returned to normal position by the spring 46%, having one end secured in the control-leverv 46 and its other end fastened in the tifip-lever-'fll For the purpose ot'allowing the controllever to be operated from a distance, the support 32 is provided'with an opening into which there is screw-threaded a sleeve 58 oit a Bowden-wire device 54 (seel Fig'. 4a) 'sothat the operating end 55 ot' the Bowden-wire is in the path of an arm 56 bent laterally trom the controlllever 46. When the fBowdenwire is operated, the control-lever is movedy from the position shown in full lines'iur Fig.

l to that shown in dotted lines, and this, as above explained, allows the trip-lever. to

function.

By holding 'l the control-leif'er Ll()Y in de.-y

pressed position, either byY operationot the key 52 or the Bowden-wire 55, the cam-eurl'ace 49 thereof is held out of rangeo the end V50 ot the triplever 43.' Consequently, so long as'tliis control-leverl is held in this position, the Vcams fen the puliey 24, will continue to oscillaterthe! vane 3,8 and cause the intermittent but continued operation ot' the back-space key-lever 26.

'Hence, when theoperator desires` to re- .turn'the carriage a large extent, the controllever all is held indepressed'position until the'carriage reaches the position desired.

c It should be understood that in its .broader aspect-s this invention is not limited tothe idea of only operating the back-space mech-r anism by power, but also embraces the idea Y of operating any part'of the machine byr the.y

record; power means adapted to drive t `nio vino" the carriage in a returni h Y C Y ,v

:"VVhile one form of the invention has been described and illustrated indetail, it should be'understood that the invention is not limited to this particular form but that variations and modifications may be made within the scopeA of the invention and portions of the improvements may be used without others. i
